PPK is called Post-Processed Kinematic GNSS, i.e., post-processed/offline RTK. The fundamental theorem of RTK and PPK is the same, all are based on Carrier-phase Differential GPS/GNSS technology. Actually, PPK is more accuracy than RTK. Since RTK is a real-time solution, a lot of real-time issues (for example. data link from the base to rover cause the base station data missing) will degrade the RTK accuracy. Also RTK only use the data forward, it is normally generate a forward solution. But PPK can use all the data in offline mode, which can process the data in reverse order, which will generate a backward solution. By combining the forward solution and backward solution, PPK can provide better accuracy and more robust solution.
Hi. I’m not saying your wrong, but I believe RTK would be the more ease of use and less accurate. Yes ppk needs more equipment , but when I collect data i create network solutions with multiple vrs base station up to 10 miles and use the observation file to correct my base point used when flying. You also failed to mention that you should use a ppk solution if say a datum outside of the project datum. The VRS system in Florida can only use nad83/2011, but some flights I’ve had where needed to be collected in nad83/90 which is still a fairly common datum. I’ve actually flown aerial LiDAR with an imu that can only be post processed in nad83/1990 with applanix pospac and project specific details where needed to be in nad27/29. They were thinking about drones and geoids in 1929, and they didn’t think about any other datum correction in pospac. Needless to say I learned a lot and went over budget lol.
Network solutions are dependent on the baseline distance from the nearest base. Using a local base (radio link) or ppk is far more accurate. Great video, thanks!

100% Least this guy knows what's he's talking about 😅

Great boys to make it clear. Awesome work

This was great! Very detailed. You guys rock!
what is rtk in drone
Emlid R2 is based on Ublox F9P chipset, which do no support have L5, it only support L1+L2
Thx guy's
RTK screwed me many times. PPK all day any day
Haven't you ever heard of unobtrusive Lavalier mikes? Please get one (each)
